Public Service Sectors require professional and innovative public officers to support economic growth. Multiple regression is used in this study to examine the research hypotheses of knowledge-intensive public services in the Indonesian Development Department in Greater Jakarta. The empirical findings demonstrate that knowledge development and pro-social behavior are significantly associated with knowledge-intensive public services. While training and development are essential tools for improving public sector officers' knowledge, when knowledge development and pro-social behavior are combined, they can have a greater significant impact in developing knowledge-intensive public services. Furthermore, the research revealed that knowledge development alone is insufficient to ensure qualified public service officers in the public sector. In conclusion, a more significant impact on knowledge-intensive public services can be achieved when knowledge development is combined with pro-social behavior.Public Service Sectors require professional and innovative public officers to support economic growth.
